As the following program demonstrates, g++ 1.35.0/sun3 handles inlining
of member functions (whose bodies are contained within their containing
class declaration) in a bass-akwards way.  Specifically, if a given
class declaration contains two member functions, and if one of these
member functions is "inline" and if the other member function contains
a call to the "inline" function, the call will *only* be inlined if
the "inline" function appears *** after *** the body of the calling
function!!!!!!!

			enilni

The reason for this "enilni" feature has to do with the order in which
g++ parses and compiles member functions.  Apparently, member functions
are "processed" by g++ in a "right-to-left" ordering, so that if you
want a member function inlined everywhere, you should put it *last*
in your class declaration, or better yet, place the body outside of
the class declaration altogether.

I have no idea how to fix this problem right now, but I hope that it
will be fixed so that "inlining" will take place "as expected", i.e.
in a top-to-bottom fashion, rather than in the current "bottom-to-top"
fashion.
